We'll need fmod and SDL.


There is some stuff in here on getting set up to build SDL apps with
[[Terminus SDL and fmod under linux]] (done)
KDeveloper: http://gpwiki.org/index.php/SDL
You will need SDL, plus the SDL_image and SDL_gfx support libs. 
Available from: http://www.libsdl.org/index.php
And the FMOD sound system from http://www.fmod.org.


Typically I'll be using either Fedora or Gentoo during my porting effort.

'''FEDORA'''
Go to [http://soloforge.com Soloforge] for the latest updates!
 
 
'''1''' Install SDL and fmod:
 
yum install SDL-devel
yum install SDL_gfx
yum install SDL_gfx-devel
yum install SDL_image
yum install SDL_image-devel
yum install fmod
yum install fmod-devel
Mar 19 22:42:01 Installed: SDL_gfx.i386 2.0.13-2.2.fc4.rf
Mar 19 22:45:23 Installed: SDL_image.i386 1.2.4-1.2.fc4.rf
Mar 19 23:11:05 Installed: fmod.i386 3.74.1-1.2.fc4.rf
Mar 20 21:22:26 Installed: fmod-devel.i386 3.74.1-1.2.fc4.rf
Mar 20 21:24:32 Installed: alsa-lib-devel.i386 1.0.10-27.rhfc4.at
Mar 20 21:24:41 Installed: SDL-devel.i386 1.2.8-4

Huh.  Does that yum app go out and get the latest version too?  Slick.
I will get some source control up and running today.

<span style="color:orange">
Yep it auto-updates everything to the latest stable versions, including tracking down dependencies.

'''2''' Grab the source - John is using subversion - very l337!
 
yum install subversion
  Mar 20 20:00:03 Installed: subversion.i386 1.2.3-2.1
cd development
mkdir terminus
cd terminus
svn checkout http://xxxxx/terminus/
 
and there it is!
 
 
'''3''' Build it
 
sdl-config tells you what you need on the gcc command line:
 
[m@thedigitalmachine terminus]$ sdl-config --libs
-L/usr/lib -lSDL -lpthread
[m@thedigitalmachine terminus]$ sdl-config --static-libs
-L/usr/lib -lSDL -lpthread -lm -ldl -lasound -L/usr/X11R6/lib -lX11 -lXext
 
So let's try this:
 
g++ main.cpp -o main `sdl-config --cflags --static-libs`
 
Here's what we got so far:
 
  In file included from system.hpp:17,
                  from startup.hpp:8,
                  from main.cpp:8:
util/audio.hpp:82: error: syntax error before `*' token
util/audio.hpp:145: error: `FMOD_SOUND' was not declared in this scope
 
<font style="color:orange">
Looks like the version of fmod that Fedora wants to pull down is old (3.74).  I believe we need to go with FMOD Ex 4 (4.03.03 as of this writing).  I will pull down the code from fmod.org and build a local version.
</font>
 
<font style="color:green">
Hmmm... There are two versions of FMOD Ex, the C and the C++ version.  I had to use the C version because the C++ version is not compatable with Dev-C++ and MinGW.  Check and make sure that you have the C version of the lib installed too.
 
FYI, here is my linker options:
 
-lmingw32 -lSDLmain -lSDL -mwindows
../../Dev-Cpp/lib/libSDL_image.a
../../Dev-Cpp/lib/libfmodex.a
../../Dev-Cpp/lib/libSDL_gfx.a
 
<br>Try this:<br><br>
Download the linux tar.gz from http://www.fmod.org<br>
Notice there is both a fmod.h and an fmod.hpp in the inc dir.<br>
Put into the compile path, the compiler should compile in the correct one (fmod.h) since that is what is in my files.<br>
There are two .03 files in the lib dir, is one of those the C version of the lib and the other the CPP?
</font>
 
<font style="color:orange">
OK I'm getting to the bottom of this.  :>  Looks like FMOD Ex 4 is not open source.  The download includes pre-built libraries but no source code.  The "makefile" just copies the pre-built libraries into place.  I think that will be OK but I have to make sure I know what it's doing.  From the "makefile" script:
 
VERSION    = 4.03.03
LIBDIR    = api/lib
HDRDIR    = api/inc
DESTLIBDIR = /usr/local/lib
DESTHDRDIR = /usr/local/include/fmodex
 
I am going to uninstall Fedora's fmod 3.74 then try the makefile.
</font>
 
<font style="color:green">
FMOD is the one "pay for" piece to the game.  The built-in SDL sound libs were problomatic.  That, and FMOD allows me to use a compressed XM file format that will save me about 5M off my downloadable size.  I think that I will pay about $100 per OS license, once for Win, once for Mac, and once for Linux.  To me, it was a close call, borderline, but in the end I deemed it worth it.
